Sharing a Local Site Online With NGrok
What is ngrok?
Ngrok is a service which allows you to expose a local website to the internet. Ngrok uses HTTP tunnels, which allow you to share a site without the need for port forwarding on your router. This means local sites can be shared from libraries, corporate networks, coffee shops, and the like.
Expose a site on port 80:
ngrok http 80
This will return something like the following:
Tunnel Status online Version 2.1.3 Region United States (us) Web Interface http://127.0.0.1:4040 Forwarding http://6d51581b.ngrok.io -> localhost:80 Forwarding https://6d51581b.ngrok.io -> localhost:80 [...]
The Web Interface URL leads to a dashboard where you can monitor connection and usage info.
The Forwarding URLs allow access to your site over http and https. Since we haven't specified an encrypted endpoint, the ngrok https tunnel will point to port 80 on your local, which may cause unexpected behavior.
Tunnel to a Virtual Domain
Your local setup may support assorted virtual host domains such as myapp.locahost, prototype.localhost, etc. You point an ngrok tunnel to one of these virtual hosts using the -host-header flag.
ngrok http -host-header=myapp.localhost 80
